Like with any differential, you have a choice when it comes to locking your axle gears. The 2.5 ton rockwell axle is not different.
You can leave the differential open (or stock)no… you are building a wheeling rig right?
- You can install a locker
- You can weld the spider gears
With all other builds I would strongly recommend going with a locker for a variety of reasons. Most importantly is the streetability of a rig with a welded differential is very poor. If I was going to run a rig without rear steering, I would run lockers in the diff, just for the improved turning ability.
Now when I build Squatch, I had two extra center sections in the shop, so I could swap out to a locker in the future, and welded the piss out of the spider gears front and back. I did this because it was cheap, I had spare parts, Squatch is trail/offroad only, and I had bought a PSC front/rear hydraulic steering set up for great maneuverability. I had no problems with the axles, or center sections with the welded spiders, even with double beadlocks and 53″ michelins.
Now if you are looking for a locker because you want better maneuverability in single steer axle rigs, or even front/rear steer I would highly recommend the detroit locker. (IT IS HUGE, BEEFY, and is the only locker I have used and love it!) If you would like to purchase one and support my website click here to purchase through AMAZON
